Needed for upcoming decoder of ethernet proto which is stored in the host order and has to be converted to the network order before printing as an xval constant. This change also adds ability to provide prefix/suffix in order to enclose the printed value in something that describes the performed conversion. * nlattr.h (struct decode_nla_xlat_opts): Add prefix, suffix, and process_fn fields. * nlattr.c (decode_nla_xval, decode_nla_flags): Handle process_fn, prefix, snd uffix parameters.
strace - the linux syscall tracer
This is strace -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.
strace is released under a Berkeley-style license at the request of Paul Kranenburg; see the file COPYING for details.
See the file NEWS for information on what has changed in recent versions.
Please read the file INSTALL-git for installation instructions.
The user discussion and development of strace take place on the strace mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to strace-devel@lists.strace.io. The mailing list archives are available at https://lists.strace.io/pipermail/strace-devel/ and other archival sites.
The GIT repository of strace is available at GitHub and GitLab.
The latest binary strace packages are available in many repositories, including OBS, Fedora rawhide, and Sisyphus.
